Available data on infrared and Raman spectra of S4N4 in solid state and solutions have been verified and completed. On the basis of normal coordinate analysis an attempt has been made to define with more precision the interpretation of vibration spectra of this compound given in earlier reports.

Infrared and Raman spectra of potassium salts of N(SeO3)23-, N(SO3)23-, and HN(SO3)22- anions have been measured. Normal coordinate analysis has been used for their interpretation and characterization of bonding relations in the anions studied.

The infrared and Raman spectra of M2[V2O2(O2)4(H2O)]·xH2O and M2[V2O2(O2)4(D2O)]·xD2O (M = N(CH3)4, Cs) were measured. In the region of the vanadium-oxygen stretching vibrations, the spectra were interpreted based on normal coordinate analysis, employing empirical correlations between the bond lengths and force constants.

The infrared and Raman spectra of triphenyl compounds of Group VA elements PPh3, AsPh3, SbPh3, and BiPh3 (Ph represents the phenyl group), have been reported in the 530–100 cm−1 region. The metal-phenyl stretching and bending vibrations have been assigned with the aid of approximate normal coordinate analysis and depolarization ratios of Raman lines.

The 1:1 adducts MX4•PMe3 (M = Ge or Sn; X = Cl or Br) are prepared by recrystallization of the respective 1:2 complexes from excess MX4 acceptor. Solid state infrared and Raman Spectra and X-ray powder photographs suggest that these adducts are all trigonal bipyramidal with the ligand in an axial position. Normal coordinate calculations in C3v symmetry (axial ligand) and Cs symmetry (equatorial ligand) support this assignment. The rather high ν(MP) frequencies indicate unusually strong metal–phosphorus donor bonds in these compounds.

The infrared and Raman spectra of the series of iodo(methyl)germanes, CH3GeI3, (CH3)2GeI2, and (CH3)3GeI have been recorded. A normal coordinate analysis based on a modified valence force field confirms the a priori assignments for all of the fundamental frequencies except the torsional modes.
